i do not have one myself so please verify it by yourself. i have
used it at meetings (Jun Murai has almost every version of it) as well
as while i have been war-driving in Tokyo. nice (or bad) thing for the
latter case was that there was no access control enabled for
6to4-based IPv6 for the particular base station i've associated with:-P
I have no idea where the IPv4 access blocking was implemented.
I could not single out the issue or find workarounds, because I had
IPv6 access already :-P
